    OBJECT OF THE INVENTION
    The present invention relates to a dispensing package of liquid, viscous, pasty or powdery products, which could cause problems to be completely extracted from a package.
    The invention is within the field of packaging technologies, and especially packaging in which the extraction of the contained product is carried out by the pressure exerted manually by a user's hand on the walls of the
    10 same. BACKGROUND OF THE INVENTION
    Products such as food sauces, gels, paints, toothpastes, cosmetic creams, etc. due to physical properties, such as surface tension, humidity and viscosity, limit and hinder the extraction of said products from the containers that
    15 contain them, requiring the usual packaging resting times, shaking, etc. for the possible, and still not complete, product extraction. As an example, 15 to 20 percent of the product contained adheres to the walls inside the package.
    There are different devices in the state of the art to optimize the emptying of
    20 products with characteristics of stickiness to the walls of the containers that contain them. Document FR2800718 presents a package that contains a flexible bag inside that receives the product. Said container, having a limited travel on each pulse, has limited product extraction to small quantities. In addition, the outer body of the container requires features
    25 individuals, such as an open bottom and vertical walls, which do not allow it to adapt to an irregularly shaped container.
    Document EP505611 also presents a container with a flexible bag inside it, which allows the majority of the packaged product to be recovered but, however, remains of product in the part of the neck of the container, since the flexible bag does not reach that area. The amount of remaining product will depend in this sense on the diameter of the neck of the container. In such an invention the outer body of the container requires characteristics that limit it to not being able to adapt to any


    shape or silhouette, as it requires an opening area in the shoulder area of the body to be able to introduce the flexible bag. In addition, if the shape of the container has a silhouette along the body, this would leave areas where the flexible bag cannot reach, limiting the efficiency of the quantity of product introduced per volume of the outer container.
    The device as presented in document ES2346054 also contains a flexible inner bag, but the problem is that the product falls to the bottom of the flexible inner bag by gravity if the container is left in an upright position, thus making it difficult to extract the next product. Once you want to use. In addition, when this route of the product occurs at the bottom of the inner bag, a breakdown of the mass of the product is created due to the adhesion of the product to the walls of the inner bag, which leaves greater surface area of the product exposed to gases coming from the outside of the container through the supply hole, being exposed to be dried and deteriorated the product contained. In this device, although to a lesser extent than in that shown in EP505611 referred to above, the supply hole can also remain product.
    On the other hand, the assembly of this internal device with the outer container, is limited to being anchored to an outer container with double opening, for once the flexible inner bag is mounted, the outer body of the container is closed or sealed on the opposite side to the orifice of supply, limiting like this to be able to execute this solution in the different types of existent containers in the market. DESCRIPTION OF THE INVENTION
    The present invention solves the aforementioned problems by means of a dispensing container according to claim 1, a method of filling the dispensing container according to claim 17 and a cartridge for viscous products for dispensing packages according to claim 19. Preferred embodiments of the invention.
    In a first inventive aspect a dispensing package for viscous products is presented which comprises,
    - A container body comprising a flexible side wall with an inner face and an outer face, a bottom wall and a neck;
    - A bag, with an inner face and an outer face and a mouth,


    adapted to contain a viscous product, and arranged inside the container body, and
    - A closing head of the container body comprising a product supply opening, with a product outlet valve, said product outlet valve maintaining a retention pressure of the product to the outside, and preventing the entry of outside air into the container ,
    where,
    The bag is an elastic bag tightly connected by its mouth to the neck area of the container body, forming a first sealed chamber between the outer face of said elastic bag and the inner face of the side wall of the container body,
    the head and the elastic bag form a second sealed chamber, and
    The container body comprises a hole with an air inlet valve adapted to allow only the flow of air from the outside of the dispensing container into the first sealed chamber against a depression in said first sealed chamber.
    In the context of the invention, it is understood as an elastic bag, both that made of elastic materials, and that flexible bag that has elements that give it elasticity, such as elastic bands or meshes.
    Advantageously, the elastic bag is directly attached to the neck of the container body. Preferably the elastic bag is attached to the neck of the container body by an elastic adjustment.
    Preferably, the elastic bag is made of elastomeric material, and more preferably, elastomers selected from elastomers from polyisoprene, latex, thermoplastic elastomers, special synthetic elastomers, or silicone elastomers.
    The fundamental property that characterizes and defines an elastomeric material is its ability to experience long deformations when an effort is applied, that is, the possibility of deforming it and returning, when the stress ceases, to its dimension reversibly.


    It is known that long deformations are those that increase in size between 5% and 700% or greater. Thus, for a general plastic, when referring to its mechanical behavior, it is understood that it works in its elastic zone in deformations of less than 2% -3%.
    Alternatively, the elastic bag is made of a material selected from thermoplastic polyurethanes, polybutadiene, natural rubber, synthetic rubber, chloroprene or vinyl.
    Advantageously, the dispensing package for viscous products of the invention comprises a hermetic connection ring, interposed between the neck and the closing head of the container body, and to which the elastic bag is attached by its mouth. Preferably, the hermetic connection ring comprises a through hole, and the air inlet valve is placed in the closing head of the container body, the through hole and said air inlet valve being aligned to establish a passage channel of the flow of air from the outside of the dispensing container into the first sealed chamber in the presence of a depression in said first sealed chamber.
    The dispensing container according to the invention comes to solve the aforementioned problem of the loss of packaged product due to the impossibility of recovering it by manual extraction, the fall of the product by gravity in the inner flexible bag when the container is left in an upright position, and the disintegration of the mass of the product due to its adhesion to the walls of the inner flexible bag. The solution to these problems is achieved by the elastic bag provided inside the container body in conjunction with the arrangement of the rest of the elements involved in the first inventive aspect. Additionally, the physical elastic properties of the material with which said bag is made and the characteristics and disposition of other elements also allow to improve several aspects and characteristics of the dispensing container of the invention, such as the complete extraction of the contained product, including Remaining in the supply hole.
    Specifically, the device of the invention,
    - It allows the almost complete extraction of the product, including the product in the supply hole, leaving as a remaining product in the container between 0.1% and 4%,
    - does not allow the product to disintegrate on the walls of the container, since at all times, regardless of the quantity of product


    remaining, the elastic bag exerts a pressure on the volume of the product and maintains it as a single mass, preventing it from drying out or deteriorating and improving the shelf life of the product,
    - allows the extraction of the product, regardless of the position in which the container remains, (horizontal, inclined, vertical, face up, face down),
    - It allows product extraction, regardless of the amount of product remaining inside.
    - improves the product extraction times, that is, the time between the user acting on the device for product extraction until the product is removed from the container through the supply hole of the closing head,
    - It is independent of the outer shape of the container body, either with pronounced curves, incoming grooves, with dimensions of the opening of the lower neck to the shoulders, etc.
    - it does not require that the container body be double open to be mounted on it, allowing simple assembly,
    - allows the possibility of reusing the container body (which can be 90% of the device's weight),
    - Improves the recycling of the container body because it does not get dirty product (can be 90% of the weight of the device), and
    - It allows the container body to be of any type of material, provided that it allows some flexibility.
    In a second inventive aspect a method of filling the dispensing container of the first inventive aspect is presented, comprising the following steps:
    a) Extract the existing air in the first sealed chamber through the orifice of the air inlet valve, until reaching the maximum expected expansion for the elastic bag,
    b) Position the air inlet valve and seal it, so that it does not allow air to pass in any direction from the outside atmosphere to the sealed chamber,
    c) Fill the elastic bag with its product at atmospheric pressure or


    superior, and
    d) Place the closing head of the dispensing container, so that a tight seal occurs between the container body and the bag.
    Advantageously, stage a) of extraction of air from the sealed chamber is carried out, either by means of a pressure applied on the inside of the elastic bag, or by means of a vacuum pump connected to the orifice of the inlet valve of air.
    In a third inventive aspect a cartridge for viscous products is presented, for dispensing packages comprising,
    - A bag, with an inner face, an outer face, and a mouth, 10 adapted to contain a viscous product, and
    - A closing head adapted for closing a container body, with a top wall and a side skirt, comprising a product supply hole, with a product outlet valve, said product outlet valve maintaining a retention pressure of the product to the outside, and preventing
    15 outside air inlet to the container,
    where,
    The bag is an elastic bag hermetically joined by its mouth to the inner area of the head where the upper wall and the side skirt converge, the head and the elastic bag forming a sealed chamber.
    All the features included in this document (including the claims, the description and the figures) and / or all the steps of the described method can be joined in any combination, with the exception of combinations of mutually exclusive features and / or stages. DESCRIPTION OF THE DRAWINGS

    A dispensing container for viscous products according to the invention is shown in the figures. The dispensing package for viscous products comprises a container body (1) comprising a flexible side wall (1.1) with an inner face and an outer face, a bottom wall (1.2) and a neck (1.3), a bag (2 ), with an inner face and an outer face and a mouth (2.1), adapted to contain a viscous product (9), and arranged inside the container body (1), and a head
    (4) of closing the container body (1) comprising a supply hole (8) of the
    product (9) in which a product outlet valve (8.1) is located, a valve that prevents outside air from entering the container.


    The bag (2) is an elastic bag tightly connected by its mouth (2.1) to the neck area (1.3) of the container body (1), forming a first sealed chamber (5) between the outer face of said elastic bag (2) ) and the inner side of the side wall (1.1) of the container body (1). In turn, the head (4) and the elastic bag (2) form a second sealed chamber (6).
    The container body (1) comprises a hole (10) with an air inlet valve
    (10.1) adapted to allow only the flow of air from the outside of the dispensing container into the first sealed chamber (5) before a depression in said first sealed chamber (5).
    The dispensing package, specifically the elastic bag (2), is capable of adapting its volume to the remaining product (9) while exerting a compacting force (or grouping) on said product. The elastic bag (2) is collected, folded, or adjusts its volume to the volume of product (9) remaining due to the intrinsic elastic force thereof.
    In a first particular embodiment, as can be seen in Figures 1 and 2, the dispensing package comprises a hermetic connection ring (3), interposed between the neck (1.3) and the closing head (4) of the container body (1) , and to which the elastic bag (2) is attached by its mouth (2.1). As can be seen in figure 2, this hermetic connection ring (3) joins the neck (1.3) of the container body (1), the bag
    (2) elastic and closing head (4).
    Advantageously, as can also be seen in Figure 2, the hermetic connection ring (3) comprises a through hole (11), aligned with the valve (10.1) placed in the closing head (4) of the container body (1), to establish a passage channel for the flow of air from the outside of the dispensing container into the first sealed chamber (5) before a depression in said first sealed chamber (5)
    Advantageously, the valve (10.1) is placed, on the flexible side wall (1.1) or on the bottom wall (1.2), of the container body (1).
    Advantageously, the neck (1.3) has at least one perimeter shoulder (12) that adjusts in at least one receiving area (13 ') provided for this purpose on the inner face of the hermetic connection ring (3), and in turn, the ring Hermetic connection (3) has on its outer face (3.2) at least one perimeter shoulder (14) that adjusts in at least one receiving area (13) also provided for this purpose on the inner face of the head (4).


    Advantageously, the hermetic connection ring (3) comprises an upper wall
    (3.3) projected inwards, preferably perpendicular to the vertical wall (3.1), adapted to rest on the upper edge of the neck (1.3).
    In a second embodiment, the elastic bag (2) is attached directly to the neck
    (1.3) of the container body (1), achieving a total tightness between the elastic bag and the container body.
    Advantageously, the elastic bag (2) is attached to the neck (1.3) of the container body (1) by means of an elastic adjustment, as can be seen in Figures 3 to 6.
    Advantageously, the neck (1.3) has at least one perimeter shoulder (12) that adjusts in at least one receiving area (13) provided for this purpose on the inner face of the head (4).
    According to any of the described embodiments, advantageously, the head
    (4) comprises a tubular projection (15) towards its interior that is located inside the elastic bag (2) through its mouth (2.1). Advantageously said tubular projection (15) comprises at least one through hole.
    Preferably, the length of the tubular projection (15) is equal, or slightly greater, to half the maximum drop length of the elastic bag (2) within the container body (1).
    Said tubular projection (15), as opposed to a geometry of the elastic bag type, presents as an advantage during product emptying that the elastic bag (2) adapts to the internal geometry of the tubular projection, thus allowing greater extraction of device product
    Again, according to any of the preceding embodiments, the outlet valve (8.1) is a drip valve. Likewise, advantageously, the valve (10.1) is a unidirectional valve or with manual means, being in this case a hole that can be covered with one of the fingers of the user's hand during the emptying of the product, and is released in the moment that no longer offers pressure on the container body (1), thus allowing air to enter the chamber (5) and thereby recovering the initial shape of said container body (1).
    Finally, in any of the described embodiments, the product supply hole (8) of product (9), advantageously, as can be seen in Figures 5A and 5B, a truncated conical projection (8.2) towards the outside of the head (4 ) from


    closing. Specifically, Figure 5A shows the elastic bag (2), in dashed line, before its filling, and Figure 5B the bag, in continuous line, adjusted to the inner surface of the conical trunk projection (8.2) of the closing head (4). The adjustment of the bag to the inner surface of the projection (8.2) allows, if possible, a greater extraction of product from inside the bag (2) of the container container.
    With respect to the second inventive aspect of the invention, that is, the method of filling the dispensing container according to any of the described embodiments, this comprises the following steps:
    a) Extract the existing air in the first sealed chamber (5) through the hole
    (10) of the valve (10.1), until reaching the maximum expected expansion for the elastic bag (2),
    b) At the time of the maximum expansion planned for the elastic bag (2), the valve (10.1) is placed and sealed, so as not to allow air to pass in any direction, that is, from the outside atmosphere to the waterproof chamber (5), or vice versa,
    c) Fill the elastic bag (2) with its mouthpiece (2.1) at atmospheric pressure or higher, and finally,
    d) Place the closing head (4) of the dispensing container, so that a tight seal occurs between the container body (1) and the bag (2).
    Advantageously, stage a) of extraction of air from the sealed chamber (5) is carried out, either by means of a pressure applied on the inside of the elastic bag (2), or by means of a vacuum pump connected to the hole ( 10) of the valve (10.1).
    The inverse process, that is to say, the emptying of the dispensing container, is carried out without keeping any valve sealed, exerting a pressure with the user's hand on the container body, thus creating a decrease in the volume of said container body and thereby an overpressure in the chamber (5) created between the elastic bag
    (2) and the container body (1). At the moment that pressure is exerted on the container body (1), it will tend to recover its original shape creating a depression in said chamber, at which time it causes the valve to open (10.1) and this allows air to enter exterior until complete recovery of the container body shape.


    Test
    To demonstrate the benefits and characteristics of the dispensing container of the invention, the following test was carried out.
    Used materials:
    5 Container body (1) typical for food sauces with:
    - 250ml capacity,
    - made of PET plastic material,
    - head (4), or cover, made of polypropylene with silicone drip valve (8.1).
    - bag (2) of elastic latex material.
    10 The perforating body (1) of PET plastic material was perforated to act as a one-way manual action valve (10.1). Said hole was obtained with the fingers of the hand while pressing the container body (1) to extract the sauce, thus preventing the entry of air into the chamber (5) created between the bag
    (2) of elastic material and the container body (1) and the hole was released when it ceased
    15 the pressure, allowing said orifice released or valve (10.1) the entry of air into the chamber (5) created between the bag (2) of elastic material and the container body (1).
    The latex bag (2) had a length of 8 cm and a maximum outside diameter of 2 cm., And was adjusted to the neck (1.3) of the PET container body (1) by a tight elastic fit.
    Once the adjustment is made between the elastic bag (2) and the neck (1.3) of the body
    20 container (1) the elastic bag (2) was blown by its mouth (2.1), at that time coinciding with the mouth or neck (1.3) of the container body (1), allowing the bag (2) to adapt to the inner sides of the flexible side wall (1.1) and bottom (1.2) of the container body (1).
    At the time of maximum elongation of the elastic bag (2) already adapted to the
    25 the internal geometry of the container body (1) the hole or valve (10.1) created on it was obtained, so as to prevent the entry of air into the chamber (5) between the container body (1) and the elastic bag ( 2). This chamber (5) is almost non-existent, being a total vacuum in the optimal case, or a quasi-vacuum when this could not be achieved. By preventing the entry of air through the hole or valve (10.1), the
    30 elastic bag (2) does not recover its original form, since its intrinsic elastic force does not


    it can overcome the void formed between it and the container body.
    Thus, with the bag fully adapted to the interior geometry of the container body (1), it was filled with product (food sauce) at atmospheric pressure, and once filled it closed with the head (4) with a drip valve (8.1) of silicone. Once the dispensing container was closed, the body hole was deobtured. At this time the system was ready to work.
    It is key that for the non-drip silicone valve (8.1) to leave its resting state, a force must be applied on it, acting as a check valve, and that it is able to withstand the force with which the elastic bag ( 2) drives the product. The force made by the elastic bag (2) must be less than that required by the silicone valve (8.1) to exit the resting state and allow its opening for the product exit. In the event that the force of the elastic bag (2) is greater than that of the retention of the silicone valve (8.1), the product would leave the dispensing container without requiring pressure on it.
    In this way, the condition is that it is an elastic material that performs the least force on the packaged product, it is only of interest that it be able to be collected in the least amount of volume possible, because all the force that this elastic material makes on the product must be braked by the valve (8.1) arranged in the head or cover (4). For this, elastic materials with great stretching capacity are ideally needed.
    In this test, the elastic bag (2), after being adjusted to the neck (1.3) of the container body (1) had an initial resting volume (without being stretched) of 25 ml. The bag (2) was stretched to adapt to the internal geometry of the container body (1) and generated a dispensing container with an internal volume of 250ml.
    The product (sauce) was emptied by exerting pressure with the fingers on the flexible plastic container body (1) and sealing the created hole (10.1), with the fingers at the time the pressure was exerted on the container body (1 ).
    To calculate and compare the amount of product extracted from the dispensing container with elastic bag (2) on the current containers sold for sauces, heavy successive were performed. Knowing the weight of the different components and the weight of the quantity of product introduced, the amount of product remaining could be evaluated without being able to be extracted in all cases. The weights of these components were the following:


    Description Weight (g)
    PET container body 20.5
    Closing head with silicone drip valve 9
    Elastic bag 0.49
    Thus, the initial set weight, packaged product (sauce) and dispensing container was 290.97 g.
    The results obtained are reflected in the following table.
    Current system Current system, shaking strongly and taking timeoutsSystem of the invention.
    Product that cannot be extracted (g) 52.1931.312
    Product that cannot be extracted (%) twenty120.7
    Finally, in relation to the last aspect of the invention, the cartridge for viscous products, as can be seen in Figures 7A and 7B, is adapted to be placed in a dispensing container, so that it is intended for sale. or commercialization independently, and that it be used as a replacement for a dispensing container when its quantity of original product is used up.
    The cartridge (16), comprises, a bag (2) and a closing head (4).
    The bag (2), adapted to contain a viscous product, has an inner face, an outer face, and a mouth (2.1).
    For its part, the closing head (4), adapted for closing a container body (1), as can be seen in Figure 7B, has an upper wall (4.1) and a
    15 side skirt (4.2), and comprises a supply hole (8) for the product (9), with a product outlet valve (8.1). Said product outlet valve (8.1) maintains a retention pressure of the product (9) towards the outside, and prevents the entry of outside air.


    The bag (2) is elastic, and is tightly joined by its mouth (2.1) to the inner area of the head (4) where the upper wall (4.1) and the side skirt (4.2) converge, forming the head ( 4) and the elastic bag (2) a waterproof chamber (6).
    As can be seen, this cartridge is directly interrelated with the dispensing container described above corresponding to the first inventive aspect of the invention, while the majority of features and constituent elements of the cartridge are those related to the elastic bag and the head of closing of said dispensing container.
